The Silent Mountain by Isa Rinner

Alana, the Warrior Princess of the Werewolf Kingdom, and Favian, the Dragon King, are fated mates, but their love story doesn’t start out the way it’s supposed to.
The stoic Dragon King and the brave princess both come from a traumatic past. Alana lost the person she loved in battle, while Favian spent years in solitude and imprisonment, as his whole species almost became extinct.
Blessed by the deities as the last remaining golden dragon, it’s on Favian to lead the remaining dragon shifters back into prosperity and rebuild their kingdom.
Alana and Favian are not ready to accept the mate bond, but they also don’t want to dismiss it immediately. Alana moves to the Silent Mountain, the dragon kingdom set high in the icy mountains, to learn more about the dragons and their mysterious king.
Whilst these two lonely souls become acquainted with each other, a new, unknown danger lurks around the corner, ready to disrupt the newfound peace of the dragons once more.
This time, however, the dragons have the Warrior Princess with the fiery hair on their side, and she is ready to fight for what she loves.
